New member here so bare with me...
I have a 04 Accord v6, its actually my wife's car! Last Saturday she drove it around town running a few errands a/c working fine. Sunday got in it to go to the gym and A/C not cooling, she finished at the gym got in it and A/C working again.. So later that afternoon I went to see if it was still working A/C not cooling again, popped the hood and the compressor clutch is not engaging. Monday I drove it to work to see if i could check a few things, check the clutch relay under the hood and its fine, used the jumper wire trick in that fuse location and clutch kicks in and out like it should. On Tuesday i brought it to a small shop to see if they could figure somethings out and the guy told me he ran some electrical tests and told me the relay is not getting ground to the PCM, it is getting 12v power but no ground.. He said he can't do anything further because it's out of his league, i would have to bring it to a dealer.... So I did, brought it to the stealership and they ran diagnostics and said I need a new PCM, they quoted me $1300 to do this!

Would anyone have any similar issues or any input on this? Maybe what wire is ground from relay to PCM, or something I can test to figure out why the PCM is not getting ground...

Again everything is working as it should with the jumper in the relay slot.... Thanks in Advance!!!
